9 Claims.

My invention relates to demountable-wheels for automobiles or the like; l An important object of the invention is to provide means whereby the wheel maybe removed I from the axle, without removing any part of the wheel, excepting the wheel cap.

A further object of the invention is to provide a demountable wheel which is of simple and practical construction, formed of few parts, which is easy to manipulate, and reliable in use. p

A further object of the invention is to provide a demountable wheel so constructed that it may be placed into position without the necessity of turning the wheel to any considerable extent.

Other objects andadvantages of the'invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and inwhich like numerals are employed to designate like parts throughout the same, H

Figure 1 is a central vertical-transverse section through a demountable wheel embodying my invention,

Figure 2 is a longitudinal section taken on line 22 of Figure 1, parts omitted, I A

Figure 3 is a similar View taken on line 33 of Figure 1,

Figure 4 is a central vertical longitudinal section through the wheel hub, associated elements being omitted and the axlehub member being shown in elevation, and, I

' Figure 5 is a perspective View of one .of the bolts.

In the drawings wherein for the purpose of illustration is shown a preferred embodiment of my-invention the numeral ID designates an axle hub member, as a whole, comprising an, inner axle hub ll, which is rotatably mounted upon the spindle H. of the axle, in any well known or preferred manner. Preferably formed integral with the inner hub H is a disk l3, carrying the usual brake drum M. Disposed upon the outer side of this disk is a hub drum l5, rigidly attached thereto by means of rivets IE or by any other suitable means. This hub drum is circular in'cross-section, and concentric with the disk i3 and brake drum l4, and tapers outwardly, as shown.

The numeral ll designates a wheel hub, carrying spokes I8, which aresecured to a rim l9.

WhileI have shown a wire wheel the'invention is not restricted to any particular type ofwheel. The wheel hub ii has' its'inner and outer ends open and its outer end is adapted to be covered by a removable cap 20.

The wheel hub I1 is circular in cross-section and tapers outwardly and is adapted to be inserted upon the hub drum l5. The wheel is preferably provided upon theinner side of its periphery with longitudinally extending grooves 2i, i

which are preferably longitudinally tapered, de- 5 creasing in width outwardly, and these grooves receive tapered longitudinal ribs 22, adapted to flt therein. The ribs 22 cause the wheel hub and hub drum to interlock against relative rotary movement, and also preferably retain the wheel hub and hub drum I 5 radially spaced. Due to the tapered arrangement of the wheel hub I l and hub drum I5 and the associated elements these parts may be readily separated. The number of interfita; ting grooves 29 and ribs 22 may be varied, and 15 these parts may also be varied in size and shape,

as may be found advantageous. 'I also contemplate providing the wheel hub I! with a radially extending flange 23, at its inner end, and to provide the inner side of this flange with ribs or teeth 24,

to interflt with ribs or teeth 25, formed upon the outer face of the disk I3. These interfitting ribs or teeth constitute means to prevent relative turning movement between the wheel hub I1 and the hub member ID, and if desired, the ribs 22 and grooves 2| may be used alone, or in combination with the interfltting teeth 24 and 25, or the interfitting teeth 24 and 25 may be used without the ribs 22. a

The disk I 3'is provided with an outwardly bulgdo ing annular portion 26, having openings 27 formed therein which are preferably square in cross-section. Adapted for insertion within the openings 21 are looking bolts 28, having portions 29 which are square in cross-section and are loosely held in the openings 27, so that the bolts may be laterally swung therein, within limits, but cannot turn therein upon their longitudinal axes. The bolts 28 have outer reduced cylindrical screw-threaded portions 30, carrying locking lugs 3 l and nuts 32. The lugs 3| are provided at their outer ends with inclined jaws 33, engaging over the outer faces of an annular flange 34, arranged within the wheel hub I1, and preferably formed integral therewith. The screw-threaded extensions or portions 33 of the locking bolts pass through radial slots 35, formed in the flange 36 of the hub drum 5. The flange 35 is pressed inwardly with respect to the hub drum l5, and is permanently spaced from the 50 flange 34.

' cluding a hub drum provided atfitsouter end with an inwardly directed flange having generally radialslot's, a wheel including a wheel hub detachably mounted upon the hub drum, a flange on the flange, and nuts carried by thei boltsto engage the her H]. To remove the wheel, the bolts 32 are unscrewed for a suitable distance but not removed w from the bolts 29. This will permit the jaws 33 of the lugs 3| to clear the transversely inclined flange 3t, whereby the bolts 29 may be swung inwardly, such bolts swinging-laterally within the openings 2i. The bolts may now be swung inwardly out of the slots 35. u The wheel hub II may now be shifted longitudinally outwardly and removed from the hub memberin. l The opposite of this operation takes place when the wheel hub l! is returned upon the hub member. d It is to be understood that the form of my inv vention'herewith shown and described is to be taken as a preferred example of the same and that various changes in the shape,i.size, .and'an rangements of parts may be resorted to without, departing from the spiritvof my invention or the scope of the sub-joined claims.
